In daily life we encounter multiple sources of sensory information at any given
moment. Unknown is whether such sensory redundancy in some way affects implicit
learning of a sequence of events. In the current paper we explored this issue in
a serial reaction time task. Our results indicate that redundant sensory
information does not enhance sequence learning when all sensory information is
presented at the same location (responding to the position and/or color of the
stimuli; Experiment 1), even when the distinct sensory sources provide more or
less similar baseline response latencies (responding to the shape and/or color
of the stimuli; Experiment 2). These findings support the claim that sequence
learning does not (necessarily) benefit from sensory redundancy. Moreover,
transfer was observed between various sets of stimuli, indicating that learning
was predominantly response-based
